“This paved/gravel interurban trail leads from Issaquah to Preston.”
— Eric Ashley
While it may test the fortitude of younger children, older ones can certainly handle this trail's gentle grades and moderate length.
This commonly used interurban trail starts in Issaquah off of the East Lake Sammamish Trail and climbs very gradually eastward through Grand Ridge Park and Highpoint to end at the SE High Point Way Road in Preston. From there, it's possible to follow the bike lane along the road for a short distance to connect to the Preston-Snoqualmie Trail.
